SPECIFICATION forming part of Letters Patent No. 691,093, dated January14, 1902.

Serial No. 69,055- (No model.)

To all whom, it mag concern:

Be it known that I, CHARLES Honcn BAG- LEY, a citizen of the UnitedStates, residing at Hoboken, in the county ofHudson and State of NewJersey, have invented certain new and useful Improvements in Milk-Cans,of which the following is a full and complete specification, such aswill enable those skilled in the art to which it appertains to make anduse the same.

The object of my invention is to provide a receptacle for milk and likefluids with a removable cover provided with means for securely lockingsuch cover to the receptacle, whereby tampering with the contents ofsuch receptacle while in transit will be absolutely prevented.

To such end my invention consists, in substance, of a receptacle havingan outwardly-' flaring circular orifice provided at the top with aninner circumferential groove formed by an inwardly-extendingwire-strengthened flange; acoverhavingadownwardly-depending centralstopper portion fitting into the portion of the orifice below the flareand a cover portion orplate extending over the flare; a bolt-compartmentin the upper part of the cover; a door for such bolt-compartment; a lockfor the dooractuated byaremovable key; sliding bolts located in thebolt-compartment andextending through the walls thereof, adapted whenpushed outward to lock the cover upon the receptacle by coaction withthe inwardly-extending top flange, and means for locking the slidingbolts when in the outward position against accidental displacement; amaster-key for each of a large number of the receptacles, and anindividual key for each of the receptacles or for each of a smallplurality thereof.

In theaccompanying drawings,forming part of this specification, in whichlike characters of reference designate corresponding parts in theseveral views, Figure 1 is a side View in elevation of my improvedmilk-can or fluidreoeptacle. Fig. 2 isa top plan View thereof, the doorof the bolt-chamber being closed, a portion thereof being broken away inorder to show the lock mechanism. Fig. 3 is a view similar to Fig. 2,the cover being shown in the open position. Fig. 4 is a View thereof incentral vertical section on the line a a of Fig. 3 looking in thedirection of the arrow, the cover, however, being in this case shown inthe closed position, as in Figs. 1 and 2; and Fig. 5 is a detailed View,on an enlarged scale, of one of the lock-bolts in position.

In the drawings, A designates the receptacle, and B the cover, suchreceptacle being usually provided with a central circumferential orificeportion 10, smaller than the main body of the receptacle, from whichextends upward the outwardly-flaring mouth portion 11, provided at itsupper end with the inwardly-turned flange provided in its inner edgewith astrengthening-wire 13, over which the sheet metal of thereceptacle is turned to hold suohwire in position in the well-knownmanner, so as to leave a circumferential groove ltbelo w such flange andwire,asshown. The cover B, like the receptacle, is usually of theWell-known milk-can form shown, consisting of a dished cover piece orplate 15, from the inner side of which extends downward a centralcircular stopper-piece 16. In myimproved form of milk-can andfluid-receptacle such stopper is provided near the top with a centraltransverse plate 17, above which is the lock-bolt chamber 18, and uponthis plate upon either side are secured two keepers 19 and 20, throughwhich reciprocate back and forth the lock-bolts 0. Such lock-b0] ts Oare provided at the rear inner ends with upwardlyextending handle orthumb portions 21 and with slots 22 and 23, which slots are adapted toengage, as hereinafter explained, with the keepers 19 and 20 when in theoutward or looking position, (shown in Fig. 4,) the slots 22 engagingwith the keeper 19 and the slots 23 engaging with the keeper 20, andwhen in the rearward or unlocked position (shown in dotted lines in Fig.3) the slots 22, engaging with the keeper 19, a spring 24, secured tothe under side of each of the lock-bolts O, of any desired form, servingto keep the lock bolts 9 5 pressed up against the keepers, so that whenin registry with such slots, whether in the outward or inwardposition,the same will be firmly locked against displacement by jarringor other accidental means, a detail of one of such bolts and the keeperspartially in section being shown in somewhat an enlarged scale in Fig.5. As will be seen on examination of Fig. 4, when the lock-bolts are in,the outward or looking position by reason of their extending outwardthrough the wall of the lock-bolt chamber 18 into the annular groove 14under the flange 12 they will in such position firmly and securely lockthe cover B upon the receptacle A and that by reason of the flange beingannular no adjustment or seeking for proper position will be necessary,as no matter in what position the cover may be when it is once pusheddown into position the bolts 0 being shot outward will pass under suchflange at some portion thereof.

The cover B is provided at the center with an orifice 25, usually of therectangular form shown and provided with a cover 26, usually hinged tothe cover by means of a hinge 27, which cover is provided with a lock28, of any desired form, adapted to be locked and unlocked by means of aremovable key 29. By this arrangement it will be seen that in dairies ormilk-supply houses or those of other persons vending liquids uponfilling the receptacle with the required quantity of such liquids andplacing the cover in position thereon, inserting the hand through theorifice 25, springing the bolts back into the locked position, (showninfulllinesin Fig.4) closing down the cover or door 26 by means of thekey 29, looking such door 26 in the closed position by throwing outwardunder the side of the orifice opposite the hinge 27 the lock-bolt 30,such receptacle will be locked against interference by unauthorizedpersons, whereby dilution, contamination, or theft of the milk or otherfluid contained in the receptacle will be absolutely prevented.

Usually where the milk or other fluid is dispensed to a large number ofdilferent persons the locks 28 are so formed that they may be providedwith a master-key, which will fit a large number or all of the cansowned by one dispenser and also so formed that small numbers of themwill also open to individual keys, which will not fit any of the locksof others of such cans except those belonging to that particular series,only the person to whom such small series is delivered being suppliedwith an individual key opening the receptacles of such set or series,whereby the tampering by one customer with the milk or fluid intendedfor another customer will be absolutely prevented.

It will be apparent that changes in and modifications of theconstruction herein dessroes scribed may be made without departing fromthe spirit of my invention or sacrificing its advantages, and I reservethe right to make all such alterations therein and modifications thereofas fairly come within the scope of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a device of the class described, a receptacle provided with atubular neck or orifice having an outwardly-flaring rim at the topthereof, said rim being provided at the top edge thereof with aninwardly-curved annular portion forming an annular groove, a removablecover provided wit-h a central tubular portion adapted to enter saidneck or orifice, said cover being adapted to rest on the top flange orrim of the neck or orifice portion and said central tubular portion ofsaid cover being provided with a transverse plate havingdiametrically-arranged keepers,at the opposite sides thereof, slidinglocking-bolts mounted in said keepers and passing through each sideorifice in the tubular portion of the cover and the outer ends of whichare adapted to enter said annular groove, said cover being also providedcentrally of the top with an opening closed by a hinged lid orsupplemental cover and means for locking said hinged lid or supplementalcover, substantially as shown and described.

2. In a device of the class described, a receptacle provided with atubular neck or orifice having a flaring top flange at the top of whichis an annular groove, a cover adapted to rest on said top flange andprovided with a depending central tubular portion adapted to enter theneck or orifice of the receptacle, said central tubular portion of thecover being provided with radially-arranged lockingbolts adapted toenter said groove and said cover being also provided centrally of thetop thereof with an opening closed by a hinged door and means forlocking said door, substantially as shown and" described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 18th day of July,1901.

CHARLES HODGE BAGLEY.
